Abstract

The invention belongs to the field of environmental risk assessment and particularly relates to an evaluation method of risk levels of dangerous substances of a mining industry. The evaluation method of the risk levels of the dangerous substances of the mining industry is characterized by firstly utilizing a dangerous substance risk level function, an ore bed safety degree function, a tailing pond safety risk level function and a corporate environmental management risk level function to compute a substance risk numerical value M, an ore bed safety risk numerical value K, a tailing pond safety risk numerical value W, and a corporate environmental management risk numerical value G, and then substituting the numerical value M, the numerical value K, the numerical value W and the numerical value G into a mining industry environment total risk level function for computation to obtain a mining industry environment total risk level rating numerical value I. The evaluation method of the risk levels of the dangerous substances of the mining industry achieves quantitative computation of the evaluation of risk sources of mining industry environments, standardization and scientization of the evaluation can be obtained and the evaluation results are reliable.

Description

technical field [0001] The invention belongs to the field of environmental risk assessment, in particular to an assessment method for the risk level of hazardous substances in the mining industry. Background technique [0002] The mining industry includes coal mining and washing industry, oil and natural gas mining industry, ferrous metal / non-ferrous metal ore mining and dressing industry, non-metallic mining industry and other mining industries. The mining industry is the basic industry of the national economy. Statistics show that 95% of my country's energy and 85% of raw materials depend on mineral resources. Mining methods are similar around the world. After extracting ore, crushing ore, etc., toxic chemicals are used to extract metals from the ore, and a large amount of slurry waste tailings are pushed behind flood plains or river valley dams. In the mining industry, there are various types of environmental pollution in the coal mining and washing industry, oil and nat...
